9 Installation The Commander software can be downloaded from the App Store. Power Button Commander icon. Other icons may appear, too Communications Module Figure 1-1 Before the ios device can communicate with the MNPR, the Bluetooth module must be installed. Do this by simply pressing the module into position over the locating pins on the front of the MNPR (Figure 1-2). Press the button on the side of the Bluetooth module to switch it on for use. Locating Pins Further information on installing the application is in Appendix F. Figure 1-2 1

11 Initial Setup Simply tap on the app icon to start the Commander software and you will see the main screen (Figure 2-1). In order to connect to the MNPR, the Bluetooth module must be paired with the ios device. To do this, enable Bluetooth on the ios device by swiping up from the bottom of the screen to open the Control Panel. Tap the Bluetooth icon so that it illuminates blue. A small Bluetooth icon appears at the top right corner of the screen when Bluetooth is enabled. The ios device will ask if you want to find a Bluetooth device the first time you attempt to communicate, such as trying to Read Status or Parameters (Figure 2-2). When prompted, press yes and choose from the list the ETI module you activated earlier. Further detail on this procedure and pairing the Bluetooth adapter is in Appendix E. Settings menu for changing displayed units, etc. Figure 2-1 The Settings Menu allows the user to change the units used to display parameters and settings to either Relay, Protector, or Percent, as well as choose the type of relay being configured. Current can be displayed in Relay Current (based off the 5 Amp secondary of the network protector CT), Protector Current (the actual current through the bus), or as a Percentage of the 3

12 CT rating. For example on a protector with at 1600:5 Amp CT Ratio, 2.5A (Relay Units) is equivalent to 800A (Protector Units) and 50% (Percent). Connect to Bluetooth module Figure 2-2 Verify that the MNPR is powered up, either properly installed in a network protector or powered up on the bench using an ETI (GE) or (WH) Single Phase Power Block. To test the communications, power on the Bluetooth head, tap Parameters, and then tap Read (Figure 3-1). The screen should populate with the relay s settings. If you get a Communications Failure or other message please refer to the Troubleshooting section of this manual. 4

13 Parameter Screens There are six parameter screens. Switch between them by swiping the screen left or right or by tapping the tabs above the page. Once you have completed your selections, return to the main screen by tapping the Back button. Read Button Back/Return to Main Screen Function Buttons Parameter Screens Tap Fields to Change Parameter Figure 3-1 5

14 The following function buttons are available on each of the Parameter screens: Read Reads the current state of the connected MNPR. These parameters are immediately displayed on the screen. Program Writes the parameters back to the MNPR. (available only after a successful Read) Reset Resets the MNPR to its factory default settings (useful if the MNPR is doing something unexpected or there is some uncertainty to the state of its programming). Once the MNPR has been read the settings can be viewed and modified (Figure 3-1). Note: Not all parameters and options are available on all types and styles of MNPR. If a parameter described in this manual does not appear on the screen that simply means it is not supported by the connected MNPR. Read only parameters: SN Displays the serial number of the MNPR. Ver Displays the version of the MNPR firmware. Type Displays the style of MNPR (General Electric (GE) or Westinghouse (WH)). FW Date Firmware revision date. Cycles Number of trip cycles. Main Parameters: Note: Graphical plots of the MNPR operating characteristics are provided for reference in Appendix A. Many of the following settings alter the operating regions shown on those plots. Relay State Indicates the current state of the relay (Trip/Close/Blocked/Float) CT Ratio Select the CT Ratio that matches the network protector. Reclose Volts Minimum three phase average differential voltage necessary to close the protector. The three phase average of the real part of the differential voltages (VTN*COS θ) must exceed this set point. 6

15 In Circle Close mode the three phase average of the magnitude of the differential voltages (VTN) must exceed this value. Reclose Angle Reclose curve lower limit. The protector will not close if the angle between the network voltage and the differential voltage is below this setting. Circle Close Selects the circle close characteristic. Limit Angle (Only available if Circle Close is enabled) Reclose curve upper limit in circle close mode. The protector will not close if the angle between the network voltage and the differential voltage is above this setting. Cross Phase Trip This setting allows the user to set a threshold of negative differential that will cause the MNPR to engage its trip contact. This contact will remain engaged until the negative differential is removed. The setting is compared to the three phase sum of the differentials. Typical situations that would activate the Hard Trip are: Feeder outage, rolled phases and crossed phases. Note: This feature should NOT be used in place of safe work practices. This is NOT a safety feature; it is a program feature only. Trip Mode Selects which of the five trip modes the MNPR is to use: Sensitive In this mode the MNPR will trip the protector when the net reverse power flow exceeds the set point. The three phase average of the signed vector sum of the network voltages multiplied by the currents (VN*I*COS θ)/ VNrms must exceed the set point. Time Delay In this mode the Sensitive criteria must be met for the duration of the time delay period before the network protector will open. However, if during the delay period the Instant Current set point is ever exceeded on one or more phases (such as a fault condition) the network protector will trip immediately (unless an Extended Delay is set, see below). Insensitive This mode is analogous to Time Delay mode if the delay time could be set to infinity. The network protector will not open during normal system conditions (feeder outage, etc.). It will only open when the Insensitive Current set point is exceeded on one or more phases (such as a fault condition). (The Sensitive criteria must also be satisfied for a trip to take place). Watt-Var In this mode the MNPR will rotate the trip region to ensure that the network protector will open under certain circumstances. Both the current at which to rotate and the amount of rotation can be set. 7

16 Delayed Watt-Var In this mode the MNPR will rotate the trip region to ensure that the network protector will open under certain circumstances. Both the current at which to rotate and the amount of rotation can be set. This mode allows a delayed and instant region to be set similar to the Time Delay mode while retaining the Watt-Var characteristic. Depending upon the Trip Mode, additional parameters may appear on the screen: Sensitive Trip This is the minimum reverse current necessary to open the protector. The three phase average of the signed vector sum of the network voltages multiplied by the currents (VN*I*COS θ)/ VNrms must exceed the set point. Instantaneous Current This is the current that must be exceeded on one or more phases in order for the MNPR to bypass the delayed portion of time delay mode. Time Delay This is the time in seconds that the sensitive trip conditions must persist for prior to the MNPR calling for a trip in time delay mode. Extended Delay This is the time in seconds that the trip conditions must persist for prior to the MNPR calling for a trip. This applies to the Instant portion of the Time Delay mode, the Insensitive Trip, and the Delayed Watt-Var. Insensitive Trip This is the current that must be exceeded on one or more phases in order for the MNPR to open in Insensitive mode. Watt-Var Current This is the current that must be exceeded before the MNPR will rotate the trip region in Watt-Var Mode. Watt-Var Angle This is the angle that the MNPR will rotate the trip region when the Watt-Var Current is exceeded. A negative setting rotates the trip line clockwise into the first quadrant. Phase Compensation For GE relays, the phase compensation is set automatically for standard CT ratios, or manually by selecting Special for the CT Ratio setting. Standard PC values are as follows: 5 for 800:5, 1200:5, and 1600:5 10 for 2000:5 and 2500:5 15 for 3000:5 and 3500:5 8

17 You may select between the 5 additional Parameter pages by tapping on them or sliding to them (Figure 3-2). The Read, Program, Back, and Reset buttons work as they do on the Main Parameters screen. You may make changes on all six parameter screens before programming. Anti-Pump / Phase Rotation: Function Buttons Parameters change with AP Algorithm Parameter Screens Figure 3-2 AP Mode Enables one of the two Anti-Pump algorithms. Anti-Pump algorithm - If the Pump Count is exceeded within the Pump Time further closing will be inhibited for the duration of the Pump Delay which can also be set to infinite. Pump Count If Pump Count is exceeded within Pump Time further closing will be inhibited for the duration of Pump Delay. 9

18 Pump Time Time limit in Seconds for Pump Count. Pump Delay Number of seconds closing will be inhibited. Motor Cutoff This anti-pump algorithm is analogous to a bucket with a small hole in the bottom. Every time the protector closes a Close Penalty is added to the bucket. If the Upper Limit is reached the protector will not close again until the Lower Limit is reached. The hole in the bucket will leak one unit every second. Close Penalty Number of close operations. High Limit Once reached the protector will not close again until the lower level is reached. Low Limit Level at which the protector is re-enabled. Phase Rotation Sensitivity When this option is enabled the MNPR will only close if the phase rotation currently applied matches the setting. Rotation Setting Expected phase rotation. Rotation Reading Actual phase rotation. Trip On Incorrect Phase Rotation - When this option is enabled the MNPR will trip when the measured phase rotation does not match the setting. 10

19 Relaxed Close: The MNPR allows a second set of reclose parameters to be preset that can be activated for a preset amount of time (Figure 3-3). This allows a simple method to safely coerce a network protector to close by reducing the thresholds required for closing. Figure 3-3 Relaxed RV (Reclose Volts) The reclose volts setting to be used in relaxed close mode. Relaxed RA (Reclose Angle) The reclose angle setting to be used in relaxed close mode. Relaxed Ph. Offset (Phasing Offset) The phasing offset voltage that will be will be in effect after activation. Relaxed Active Time The time in seconds that the relaxed settings will be in effect after activation. 11

20 Misc. Parameters: Figure 3-4 Close Tilt Angle This setting allows the angle, in degrees, of the close characteristic to be modified. Trip Tilt Angle This setting allows the angle, in degrees, of the trip line of the sensitive trip characteristic to be modified. Sens. Trip Delay Time delay in seconds from sense to trip. Reclose Time Delay Time delay in seconds to reclose. Close Algorithm Select between Average All Phases, All Phases AND d, Average All Angle 1, Average All Angle 2, Average All Angle 3, Circle Close and All Phases OR d. 12

21 Net. Volts too Low Lower limit for valid network voltage. Phase Select Allows the phase order of the network protector to be matched to that of the MNPR. Many styles and vintages of network protectors are wired differently and it is not always the case that the MNPR s Phase 1 will be wired to the network protector s Phase A. The purpose of this setting is to allow the display of all measured per phase values in the desired order, both on the scrolling display and in the View Data screen, irrespective of the physical protector wiring. For an example of how to set this properly please see Appendix F. Care should be taken when adjusting this setting when used in conjunction with phase rotation sensitivity. The "Phase Select" setting is applied before the phase rotation is calculated and thus it could alter the rotation measured by the MNPR. Other than the phase rotation sensitivity, this setting will have no other effect on relay operation or programming. Trip Pulses The number of times the MNPR will pulse its trip contact upon calling for a trip (one second on, one second off). After the required number of pulses the contact will remain active until the network protector opens unless the parameter Trip off after Pulses is checked. A setting of zero will simply turn the output on and hold it until the network protector opens. Phasing Voltage Offset This setting allows the phasing offset on the close characteristic to be adjusted (See Figure A-1 in Appendix A). Low Voltage Trip If the three phase average of network volts falls below this threshold, the MNPR will call for a trip of the network protector. (NOTE: This setting has no effect on the Dead Network close operation of the MNPR ) Trip Contact Off After Pulses When the relay calls for a trip, the trip contact will pulse the number of times specified in the "Trip Pulses" setting. If the network protector fails to open, the contact can either be maintained or released depending on the state of this checkbox. Adjustable Dead Network If enabled, the MNPR will assert the close contact until the set point voltage is reached on any single phase. When set to "OFF", the close contact will de-assert at 13 Volts on any single phase. IOC Enable Input Selects the auxiliary input channel that the relay will monitor to determine if Instantaneous Over Current Trip is enabled. IOC Setting Sets the threshold for the non-directional overcurrent trip characteristic. 13

22 DNP3 Settings: You may setup DNP3 communications parameters on the DNP screen (Figure 3-5). This screen applies to communicating MNPRs only. Figure 3-5 DNP Address DNP3 Address of the MNPR NWP Status Input Selects the auxiliary input channel that the relay will monitor to determine the network protector status (Open/Closed) NWP Status Type Controls the sense of the selected status input channel. An "A Contact" is closed when NWP is closed. A "B Contact" is open when network protector is closed. High Voltage NWP Scaling If this box is checked, the voltages reported via DNP3 on a communicating MNPR will be scaled up by a factor to account for the potential transformers 14

23 (PT s) in the high voltage network protector. Certain versions of the MNPR firmware allow a specific PT ratio to be selected, however older versions will just display a checkbox, which will scale the voltage by a factor of 2.2 for a 277/480V network protector when selected. PT Ratio Potential Transformers (PT) ratio used for scaling DNP3 data. Zero GE Data If checked, the current (as transmitted via DNP) will be zeroed out when the network protector is open and the differential voltage (as transmitted via DNP) will be zeroed when closed. (Protector status is derived from the previously described status input. Option is available on GE relays only) Send DNP Aux Analogs as 12 bit If this box is checked, the auxiliary analog inputs will be reported as 12 bit values via DNP3. If left unchecked the data will be sent as 8 bit values. If the box is checked and the hardware only supports 8-bit inputs, the data will be shifted to 12 bit before sending. DNP Control Inhibit Input Selects the auxiliary input channel that the relay will monitor to determine if DNP control commands should be ignored (local operation of relay only) Enable Unsolicited Responses Enables the MNPR to send unsolicited response messages. Destination Address The DNP3 address that the MNPR will be sending the unsolicited response messages. Response Timeout The total length of time, in seconds, that the MNPR will wait for an acknowledgement of an unsolicited response. Comm Board Rev This is the revision of the communications and aux I/O hardware inside the MNPR. DNP Profile Version The User Version is a user provided version number that is assigned when the profile is created. It is useful for tracking different profile versions, if changes are required. DNP Profile Hash The Hash is a computer-generated signature that identifies the profile. If any changes are made to the profile it will generate a different hash. This is useful to verify that the profile in question matches the desired profile. 15

25 Basic Setup Procedure The following describes the minimum configuration necessary to setup a MNPR. Depending upon the specific needs of the utility, this may vary. 1. Tap the Read button on the Parameters screen (Figure 3-1). This will retrieve the current MNPR s settings. 2. If unsure about the state of the MNPR, tap the Reset button on the Parameters screen to reset all of the settings to factory defaults. 3. Ensure the desired units are properly selected. (via the Settings Menu at the top of the main screen) 4. Set the CT Ratio, Trip mode and associated settings, and reclose parameters to the desired values. 5. Tap the Program button to program the MNPR. 6. Tap the Read button again, and verify that the settings programmed in step 3 are correct. 7. The relay should then be tested to verify that the trip and close characteristic perform as desired. 17

27 Relay Status Screen Tapping the Status button on the main screen will display the Relay Status Screen (Figure 5-1). This single page contains all status information. Figure 5-1 The status screen lists various items that pertain to the operation of the MNPR. The first few display the current state of the MNPR. This is the current state of the MNPR, not the network protector. 19

28 Float The MNPR is not calling for a trip or close. The network protector should maintain its current position. Trip The MNPR is calling for a trip. Close The MNPR is calling for a close. Blocked The MNPR is blocked (using the block button on the main screen). It will not call for a close even if system conditions permit. Hard Trip The MNPR will hold the trip contact on, even if the network protector is open during a cross phase condition (if cross phase trip is enabled). Phase Angle Wrong This indicates that the reason the MNPR is not calling for a close at the moment is due to the phase angle not being inside the close region. Diff. Volts Too Low This indicates that the reason the MNPR is not calling for a close at the moment is due to the magnitude of the differential volts being below the Reclose Volts setting. Network Volts Too Low This indicates that the MNPR will not close because the three phase average of the network voltage is not exceeding the Network Volts Too Low To Close setting. Using Defaults (Reprogram) The internal memory in which the MNPR stores its operating settings has become corrupt. The MNPR is operating using the default values. You should perform a reset and reprogram the MNPR. Relaxed Close Active This box will be checked when the MNPR is currently operating using the Relaxed Close parameters. Comm Board Detected This indicates whether or not the MNPR has an internal communications board. Anti-Pump Block This indicates that the anti-pump algorithm has been triggered and the MNPR will be blocked from closing. Motor Cutoff Inhibit This indicates that the motor cutoff algorithm has been triggered and the MNPR will be blocked from closing. Phase Rotation Wrong The MNPR will not close because the phase rotation reading does not match the setting. Default DNP Profile This indicates that the MNPR is not using a custom DNP3 Profile. It will use a standard DNP Point List and manually configured parameters. (See the DNP3 Setup and DNP3 Profiles Sections for additional information) 20

29 NWP Status Closed A check in this box indicates that the Network Protection Status is closed. DNP Control Inhibit Active This indicates that the auxiliary input channel selected for the DNP Control Inhibit function is in the active state and remote commands will be ignored. IOC Monitoring (Maint. Mode) Active This indicates that the auxiliary input channel selected for the instantaneous overcurrent function is in the active state and a lockout (Trip & Block) will be initiated if the overcurrent setting is exceeded. IOC Lockout Active - This indicates that the instantaneous overcurrent setting was exceeded and a lockout (Trip & Block) was triggered. The relay will continue to issue a trip until a local unblock command is issued via the relay optical port (remote unblock via DNP will NOT override this lockout). 21

31 Monitor: Monitor Screen The Monitor Screen displays the network voltages, differential voltages and relay currents of all three phases as well as the temperature inside the relay (Figure 6-1). Menu Items are available in the Monitor Screen to turn polling on and off and to set the display units. Function Buttons Polling Status Figure 6-1 Temperature 23

32 Current - The load current measured by network protector relay. It can be displayed in either of three units: Relay Units (shown in ma, based off the 5 Amp secondary of the network protector CT) Protector Units (shown in Amps, the actual current through the bus) Percent Units (shown as a percentage of the CT rating) For example on a protector with at 1600:5 Amp CT Ratio 2.5A (Relay Units) is equivalent to 800A (Protector Units) and 50% (Percent Units). Network Voltage The voltage measured at the relay N1, N2, N3 terminals with respect to ground. Note that on a high voltage network protector with potential transformers (PT's), this will not match the voltage on the network protector bus. Transformer Voltage Depending on the relay type, this will display one of three possibilities: 1. Not available. 2. The voltage measured at the relay T1, T2, T3 terminals with respect to ground. Note that on a high voltage network protector with potential transformers (PT's) this will not match the voltage on the network protector bus. 3. The network voltage + the differential voltage. This will be equivalent to the transformer voltage assuming the differential voltage does not reach its maximum value (about 18V on a Westinghouse style relay). Differential Voltage On a Westinghouse style relay, this is the real part (multiplied by the cosine of the angle) of the voltage difference measured between the relay s N and T pins. On a GE style relay, this value is obtained by measuring the current produced through a tertiary winding on the network protector CT, which is proportional to the difference between the N and T bus. Note that this quantity will not match the voltage difference measured by a voltmeter placed across the relays N and T pins. Diff Voltage Magnitude On a Westinghouse style relay, this is the voltage difference measured between the relay N and T pins. Note that on a high voltage network protector with potential transformers (PT s) this will not match the voltage difference measured across the network protector. On a GE style relay this value is obtained by measuring the current produced through a tertiary winding on the network protector CT, which is proportional to the difference between the N and T bus. 24

33 Phase Angle Depending on the state of the network protector (open/closed) this will either show the angle between the network voltage and differential voltage or the angle between the network voltage and current. Relay Temp Internal Relay Temperature. You may select degrees Celsius or Fahrenheit (Figure 6-1). Function Buttons: Read Performs a single read of the MNPR Start Poll Turn the continuous polling feature on and off (Figure 6-1). Polling does not commence until the Polling button is pressed and switched to On. Stop Poll The Start Poll button changes to the Stop Poll button during automatic polling. Tapping the Stop Poll button halts periodic polling. 25

34 Aux I/O: The Auxiliary I/O screen contains readings from various analog and digital sensors. Note: The number of inputs and outputs is dependent upon the specific hardware. Analog Input Readings Digital Output Controls Digital Input and Output Status Figure 6-2 A1 A8 Analog input readings. DI1 DI4 A check mark appears in the box if the corresponding digital input is on. DO1 DO3 A check mark appears in the box if the corresponding digital output is activated. Digital outputs are activated by tapping the corresponding control buttons. 26

35 View Waveforms Tapping the Waves button on the main screen will display the Waveforms (Figure 7-1). Figure 7-1 Read Current Reads the stored current waveforms from the MNPR and displays them. Note: Network voltage is retrieved as well. Read Diff Reads the stored differential voltage waveforms from the MNPR and displays them. V Net 1, V Net 2, V Net 3, V Diff 1, V Diff 2, V Diff 3, I 1, I 2, I 3 These check boxes determine which wave sources are displayed in the graph. 27

37 Operations The Operations screen allows manual control over the relay (Figure 8-1). Figure 8-1 Relaxed Close Causes the MNPR to operate from its relaxed close parameters (see the Relaxed Closed settings in the Parameters section described on pages 11-12). Block Blocks (prevents) the relay from tripping. Unblock Removes the block and allows normal operation. Trip Manually trips the relay. 29

38 A confirmation screen will appear before any operation will occur (Figure 8-2) and a message at the bottom of the screen will verify that the operation took place as expected. Figure

39 Help/Info The Help/Info page displays pinouts of the Westinghouse style and GE style MNPR s. You may also review them in Appendix B. Figure

41 Troubleshooting If at any time a Communication Failure message is displayed verify the following: - The MNPR is powered, either with a power block or by being installed in an energized network protector. - The Bluetooth module is securely attached and paired to the Android device and its LED is illuminated. - The Bluetooth adapter contains a 9V battery for power. Sometimes the Status LED will come on even when the battery is too exhausted to power the communications. When replacing the 9V battery be sure to note the position of the battery cover before removing it from the adapter so that the orientation will be correct when reinstalled (Figure 9-1). Battery Cover Status LED Power button Figure Ensure that the optical head is oriented correctly on the MNPR. The ETI logo on the label should face the top of the MNPR (the top is the side closest to the optical port). (Note that in some network protectors the MNPR may be mounted sideways) - When Commander is communicating with the MNPR the words Remote Login should be scrolling on the display of the MNPR - Check the window covering the optics on the relay. If it is dirty, oily, scratched, chipped, or compromised in any way communications could be severed. Try wiping it off with a clean cloth. Any glass cleaner can also be applied to the window. Also check the optics on the module for similar problems. 33

69 Appendix E. Pairing the Bluetooth Module with the ios device The ETI Bluetooth Module is used in conjunction with an ios device and ETI s Commander Software to wirelessly setup and troubleshoot an ETI MNPR. Note: The Bluetooth Module will not work with ios devices. The must be used. 1. Power on the Bluetooth module by pressing the pushbutton on the left side. The blue light on the right side will begin flashing. This indicates that the module is waiting for a connection. The module will remain on for 15 minutes after the last communication with the relay. There is no way to manually turn the module off. In the event that the blue light fails to turn on when the button is pressed, replace the 9V battery under the cover (remove the 4 screws for access and be careful to note the orientation of the cover so it may be replaced the same way). 2. Place the Bluetooth module over the optical window on the MNPR as shown below (MNPR must be powered). Serial Number Push Power button Figure E-1 61

70 4. Make sure Bluetooth is enabled on the ios device by checking for the Bluetooth icon in the upper right status bar (Figure E-2). If absent, enable Bluetooth by swiping up from the bottom of the screen to open the Control Panel (Figure E-3). Tap the Bluetooth icon so that it illuminates blue. Now open the ETI Commander app. Bluetooth Enabled Icon Figure E-2 Control Panel View Bluetooth On/Off Button Swipe up to open Control Panel Figure E-3 62

71 5. Pair the ios device and Bluetooth module by initiating a Read action from any screen (such as the Parameters or Status screens). 6. A window will appear asking if you want to search for a bluetooth module (Figure E-4). Tap Yes and it will show nearby active Bluetooth modules (Figure E-5). Maximum wireless range is feet. Figure E-4 Figure E-5 7. Select the ETI OPTO device with the matching serial number by tapping it. 63

72 8. The currently paired module will be noted on the app s main screen (Figure E-6). It will remain paired as long as Bluetooth is enabled and the module is within range. If the link is broken (such as moving out of range) you will have to find the module again as in steps 5 & 6 the next time you want to connect. If you want to pair with a different Bluetooth module, open the Control Panel as in step 4 and toggle Bluetooth off and on again. This will end any current pairing. Currently paired Bluetooth module Figure E-6 64

75 Appendix F. Phase Select Details The Phase Select setting found in the Advanced settings menu allows the phase order of the network protector to be matched to that of the MNPR. Many styles and vintages of network protector are wired differently and it is not always the case that the MNPR s Phase 1 will be wired to the network protector s Phase A. The purpose of this setting is to allow the display of all measured per phase values in the desired order, both on the scrolling display and in the View Data screen, irrespective of the physical protector wiring. Care should be taken when adjusting this setting when used in conjunction with phase rotation sensitivity. The "Phase Select" setting is applied before the phase rotation is calculated and thus it could alter the rotation measured by the MNPR. Other than the phase rotation sensitivity, this setting will have no other effect on relay operation or programming. Referring to the partial Westinghouse network protector schematic shown in Figure H-1, it can be seen that the wiring from the left bus bar goes to the MNPR s Phase C input, the middle bus bar goes to the Phase A input, and the right bus bar goes to the Phase B input. In this example, in order for the MNPR to display the phases in the proper left to right order, the Phase Select should be set to CAB. Figure F-1 67
